Permissions for cross account Amazon SNS topics - Amazon DevOps Guru

Permissions for cross account Amazon SNS topics

Use the information in this topic only if you want to configure Amazon DevOps Guru to deliver Amazon SNS topics owned by a different account than yours.

For DevOps Guru to deliver an Amazon SNS topic owned by a different account, you must attach to it a policy that grants DevOps Guru permissions to send notifications to it. If you configure DevOps Guru to deliver Amazon SNS topics owned by your account, then DevOps Guru adds a policy to the topics for you.


DevOps Guru currently only supports cross-account access in the same Region.

To use an Amazon SNS topic from another account, attach the following policy to the existing Amazon SNS topic. For the Resource key, topic-owner-account-id is the account ID of the topic owner, topic-sender-account-id is the account ID of the user who set up DevOps Guru, and devops-guru-user-name is the individual IAM user. You must substitute appropriate values for region-id (for example, us-west-2) and my-topic-name.

{ "Version": "2012-10-17", "Statement": [ { "Action": "sns:Publish", "Effect": "Allow", "Resource": "arn:aws:sns:region-id:topic-owner-account-id:my-topic-name", "Principal": { "Service": "" }, "Condition" : { "StringEquals" : { "AWS:SourceAccount": "topic-sender-account-id" } }, { "Action": "sns:Publish", "Effect": "Allow", "Resource": "arn:aws:sns:region-id:topic-owner-account-id:my-topic-name", "Principal": { "AWS": "arn:aws:iam::topic-sender-account-id:user/devops-guru-user-name" } } ] }

After you add a topic, we recommend that you make your policy more secure by specifying permissions for only the DevOps Guru notification channel that contains your topic.

Update your Amazon SNS topic policy with a notification channel (recommended)

  1. Run the list-notification-channels DevOps Guru AWS CLI command.

    aws devops-guru list-notification-channels
  2. In the list-notification-channels response, make a note of the channel ID that contains your Amazon SNS topic's ARN. The channel ID is a guid.

    For example, in the following response, the channel ID for the topic with the ARN arn:aws:sns:region-id:111122223333:topic-name is e89be5f7-989d-4c4c-b1fe-e7145037e531

    { "Channels": [ { "Id": "e89be5f7-989d-4c4c-b1fe-e7145037e531", "Config": { "Sns": { "TopicArn": "arn:aws:sns:region-id:111122223333:topic-name" } } } ] }
  3. In the Condition statement of your policy, add the line that specifies the SourceArn. The ARN contains your Region ID (for example, us-east-1), the AWS account number of the topic's sender, and the channel ID you made a note of.

    Your updated Condition statement looks like the following.

    "Condition" : { "StringEquals" : { "AWS:SourceArn": "arn:aws:devops-guru:us-east-1:111122223333:channel/e89be5f7-989d-4c4c-b1fe-e7145037e531", "AWS:SourceAccount": "111122223333" } }
